Hello,
Yes, your guess is right, your son is having headache because of
severe dehydration and electrolytes loss after
sauna. Please don’t worry as it is completely correctible. The following are the instructions that I would give to patients who come to my clinic with similar complaints:
1) Let him take ample rest by lying down
2) Allow plenty of fluids
3)
ORS sachet in 1 lit of water is to be dissolved and asked to drink frequently
4) Rehydration and replenishment of electrolytes is the key.
5) Caffeine helps reduce headache
6) For
severe headache, analgesics like tab.
Ibuprofen can be taken
It would come down by 3-4 days usually. If no improvement is seen or situation worsens, contact your GP.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Pallavi M., Anesthesiologist
